Arguably, yes. However, I ran out of energy before I could implement
that. The bollard code does very similar things but, to be honest, I
can't really be bothered at this time. If someone else wants to
implement that, I will happily integrate their patch. My feeling was
that in most places where traffic signals and crossings are, the ways
will contain points fairly close together and so the amount of way
that is affected will actually be quite small. If you find a place that
suffers from this problem, just stuff an extra point into the way 50m
from the POI!

Cheers,

Mark

PS - the bollard code limits the distance affected because it's
actually changing the access rights to the way and not just reducing
the class/speed.
